1D and 2D Nuclear magnetic resonance of new silver(I) complexes with achiral and chiral bases as ligands: Crystal structure of [Ag{(S)-(6-CH3)C5H3N-CHN-CH(α-CH 3)C6H5}(PPh3)2](O 3SCF3)

Treatment of equimolar amounts of substituted aniline or amine with substituted benzaldehyde leads to the corresponding achiral or chiral Schiff bases (L). The reaction of the bases with [Ag(O3SCF 3)(PPh3)] leads to the preparation of three or four coordinated cationic complexes, [Ag(k1-L)(PPh3) n]+ (n = 1 or 2) which have been characterized by IR, 1D and 2D NMR spectroscopy. The crystal structure of [Ag{(S)-(6-CH3)C5H3N-CHN-CH(α-CH 3)C6H5}(PPh3)2](O 3SCF3) is reported. © 2011 Elsevier B.V.
